How to make jquery.searcher search by word instead of complete string?

Apparently it searches the entire string of what in the text box rather than words. For example if i type "Respect" Aretha Franklin appears but when i search "respect dog" i want both Aretha Franklin and Elvis Presley's Hound Dog to appear.

the reason is because im implementing this search to sift through DVD's, CD-ROMS, Blu-rays etc on my project.

So if someone wants to search Action DVDs it will show all items with Action and DVD in the text. Like how normal searches are.
